Toall whom it may concern:

Be it known that I, W ILLIAM J .YouNe, a citizenof the United States of America, and a resident of Cleveland, in the county of Guy- '5 ahoga and State of Ohio, have invented certain newand useful Improvements in Liquid- Carbonating Apparatus, of which the following is a specification. I

My invention relates 'to' improvements in apparatuses for carbonating liquids; and the object of my improvement is to provide for an apparatus which is simple in construction, convenient in point of manipulation, and officient in point of operation. I attain this ob ect in an apparatus constructed substantially as shown in the accompanying drawings, in which Figure 1 represents avertical sectional view of saidapparatus complete. Fig. 2 is an en- 2o larged sectional view of a part thereof. Figs. 3 and 4 illustrate plan views of parts thereof detached.

Like letters of reference denote like parts in the drawings and specification.

:2 The vessel part of this apparatus consists of the tank A and the column B, of which the latter has secure connection with the top part of the former. (See Fig; 1.) The tank proper is provided with suitable valves 0. a

and a gage-glass I). Ate an'outlet is provided from said-tank. dand e areinlet-pipes to said column, respectively, 'for gas and liquid,

while by means of the pipe 0 auxiliary open relation is established between the top of the 3 5 tank and that of the column. Inside the column, upon a rod or tube, are mounted a series of conesE and bowls F, also a valve G,

(see Figs. 1 and 2,)-and.the rod itself is suitably supported near the foot of the colo umn, as at f. The outer surface of the cones,

as well as the inner surface of the bowls, is.

undulated. or flanged in terrace-like form. (See Figs. 2, 3, and 4.) As shown, these flanges are superimposed and form, annular 5 dripping-flanges, the drippings from one flange passing into the next flange below it. This is of positive advantage in a device of this character in view of the fact that there is'not only a continuous breaking upor atomi'zing of the liquid and enabling the molecules 'ferentdiameterybothsides of which are extomore readily absorb the gas, but in addition theliquid in breaking ,forms what might be termed a curtain from one flange to another, 'the'successive curtains being of a difposed to the action of. the gas, and as each flange is either larger or smaller in diameter than the preceding one the succeeding cur tains are of diiferent character, the flanges of I small diameter having a comparatively continu'ous curtain, while as the flanges gradually iucrease in diameter the curtains become more brokeu'in -continuity, it being understood that the amount. of liqnidldripping from one flange ,to another (after the flanges have become filled) is substantially the same,

the difference in the circumference 'oitf the dripping edges of the flanges causing the change in the character of the curtain. This change in thecharacter of the curtains is ad-' vantageous in that there is a better opportunity for the liquid to absorb the gas asthe drippings become more divided in form, while the gradually diameter increasing flanges again gradually bringvthe curtain 'to its initial form, followed by the gradually-increasi-ng division due to the increase in size of the flanges. Thesecontinual changes tend to change the relative position of the molecules, giving them a thoroughmixturaso that there is a more thorough absorption of the gas. This would not be possible were the cones and bowls provided with'plain surfaces, as in such case the one side of the liquidsheet is not per-. meable by the gas,'and hence there is not only less tendency for the rapid absorption of the gas, but this assimilation is retarded by the movement in a body of the liquid oversuch plain surface. Normally the valve G is held against the face of nozzle g which projects inwardly from cover it of column B. Pref-. erably a spring 11 is interposed between the head of said valve and the terminal of said tube D, which receives the stem j of said valve, as seen in Fig; 2. As shown, an ordinary stop-valve 7c is secured-to the outside of the cover, connected with which is pipe e,.' wherein liquid is conveyed to said apparatus. Both the liquid in pipe e and carbonic-acid gas in pipe :1 are supplied under pressure, 100

the liquid-pressure being higher than the gaspressure. The flow of liquid into column B is automatically controlled by means of valve G, from where it collects in tank A. As the tank A and the carbonating chamber or reccptacle B are necessarily gas-tight, the continued supply of gas within the chamber will gradually cause the increase of pressure within the chamberand-the tank (both being under the same conditions, owing to the presence of the pipe C) until this pressure is greater than that of the liquid, whereupon the valve G will close and cut oiif the supply of liquid to the chamber and at the same time substantially stop the flow of gas into the chamber, by reason of the greater pressure existing therein. When this pressure is reduced by the withdrawing of some of the contents from the tank, the liquid-pressure then being greaterthan the pressure within the chamber will force the valve G open and allow liquid to enter until this pressure is again secured. It will be readily understood that this increase of pressure in the tank and chamber is due to the gradual increase of the liquid in the tank, the surface of the liquid therein acting somewhat in the nature of a piston to compress the gas of the tank and chamber, so that when this is reduced by lowering the surface of the liquid in the tank the valve G will be opened, said valve operating under the greater pressure in an obvious manner. It will therefore be seen that I have provided an apparatus in which the passage of the liquid into the carbonatingchamber is controlled solely by the pressure formed within the chamber itself, and there- 'fore there is no requirement of auxiliary controlling devices located without the chamber, dispensing entirely with mechanism which will in itself control the passage or the pressure of the liquid to the chamber. In fact, a device of such a character would practically defeat the object in that thereis required a; constant andsubstantially unvarying pressure of both liquid and gas. liquid in passing through valve G is first caught in the upper trough of the uppermost bowl. Thence it overflows into the second and third trough; from where it flows over troughs of the next following cone. Thence it meets another troughed or flanged bowl, and so on until itdrips overthe last dis-k Z or what ever obstruction maybe placed in its path.

Liquids thus being thoroughly atomized or agitated can and will take up all the gas they are capable of absorbing, and since there is an auxiliary equalizing-pipe 0 provided for no trapping of gas can occur; but all incomng gas from pipe d is allowed to ascend freely in column B for being commingled with and absorbed by the falling liquid. As often as carbonated liquid is withdrawn from tank A the pressuretherein becomes reduced, whereupon afresh supply of water will enter by wayjof valve Gto be carbonatedin the manner as above described. Since the larger area The of the valve G is exposed to the gas-pressure, Y

it is evident that the latter should be supplied in sufficiently-reduced state in order to maintain the valve G on the verge of opening to replenish water in sufficient quantity for absorption of the gas which is continually supplied at or near the bottom of the column.
